You would willingly subject yourself to a keyboard condom? Those things feel so bad to type on.

Iirc macbooks also have issues with those messing up the screen. At the very least, every macbook with a keyboard condom that I have seen in real life had the keyboard outline quite visibly imprinted on the screen surface.

In fact if you scroll down on that amazon page, the product description has a link to a 'screen imprint protector' (a loose paper-linke piece of material) designed specially to protect against that issue.

If you put a condom on it and have to carry around a loose screen protected and put it on every time you close the lid, then its kind of sad to say that there's not a gigantic issue with the machine or that that's a trivial solution.

Also I've also read stories of people using those keyboard condoms and still having the keyboard break.
